 There is a feature called `"parser"` which allows you to read calendars again like this:
 
 ```rust
-use std::fs::File;
-use std::io::Read;
+use std::fs::read_to_string;
+
 use icalendar::{Calendar, CalendarComponent, Component};
 
-let mut file = File::open("fixtures/icalendar-rb/event.ics").unwrap();
-let mut contents = String::new();
-file.read_to_string(&mut contents);
+let contents = read_to_string("fixtures/icalendar-rb/event.ics").unwrap();
+
 let parsed_calendar: Calendar = contents.parse().unwrap();
 
 for component in &parsed_calendar.components {

-        CalendarComponent::Event(event) => {
-            println!("Event: {}", event.get_summary().unwrap())
